Application: kwin_x11 (5.16.1)

Qt Version: 5.12.4
Frameworks Version: 5.59.0
Operating System: Linux 5.1.12-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

1. Enable desktop effects described in the section below
2. Close any window and trigger "Fall Apart" desktop effect
3. When the effect is running, switch to another virtual desktop
4. Kwin crashes

- Custom settings of the application:

1. Fall apart desktop effect enabled
2. Virtual desktop switching effect is either desktop cube or slide. Fade desktop will not crash kwin

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
